Before engaging in detailed analysis regarding the project’s research questions, we will first run general frequencies of SDPD stops to get a sense of overall trends. This helps us determine if our expected findings are likely to show up in the data and allows us to identify any trends we did not expect. The analysis will include:
General counts and percents of SDPD stops by key fields in RIPA data, e.g., stop reason, stop result, calls for service, race, age, searches, officer assignment.
General counts and percents of stops by Gang Suppression Unit and Special Operations Unit (if available) by key fields in RIPA data, e.g., stop reason, stop result, calls for service, race, age, searches.
Quick map of stop counts by police beat and for Gang Suppression Unit/Special Operations Unit.
